Bevy 0.10

[johanhelsing]

Makes basic example work with latest bevy

• switch to bevy 0.10 when out
• fix the rest of the examples
• figure out if I got the mip_levels right

I am sorry for not having chosen a better name, but I did already port the codebase to bevy 0.10 here: #390. I've added the (0.10) suffix now. All examples are already ported. I used gpu_texture.mip_level_count() for the mip level count instead of a hard coded 1.

My pull request targets the bevy_track branch, because I hoped it could then be pulled earlier without disturbing main (Edit: I forgot I did already change that). And unlike you, I don't have the rights to start work flows. Would you mind if I open a PR for your fork and then you can use it to open a PR here for the main branch?

Ah, bummer. Don't know why I didn't see it. I'll let you continue on yours then 👍
